METHOD OF MAKING BOOK-COVERS.

Specification of Letters Patent.

Application filed November 16, 1906. Serial No. 343,665.

ments in book covers and the method of making the same, and more particularly to flexible covers.

In the drawings, Figure I shows the cloth cover and paper lining superimposed, ready for turning the edges of the cover over the lining; Fig. II shows the edges of the cloth cover turned over the edges of the lining. Fig. III shows the cover glued to the back of the book and the cover linings and inside lining in place.

In the drawings a represents a cloth outer cover with rounded corners, and b a paper lining, the latter being cut to have all sides parallel to the sides of the outer cover, but slightly shorter than the corresponding sides of such cover. The cloth is preferably stifi ened by sizing or by other means and the paper is preferably slightly stiffer than the outer cover. The book proper is shown at c, and the cover lining at (Z, d.

In making the cover the outer cover a is laid upon a table and one side thereof covered with glue. The lining Z) is then placed on the glued side of the outer cover in the manner shown in Fig. I, and the protrudingv edges of the outer cover are then folded over the edges of the lining, the glue serving permanently to unite the edges of the cover with the lining. The edge of the paper lining acts as a guide for the cloth, both at the edges and at the corners, thus making it unnecessary to use the zinc gulde usually employed. As the protruding edge of the a cloth is very narrow, the corners may easily be turned over, and the folds necessitated by the rounding are so small as hardly to be noticeable. 'The inner edge of the fold may be made less noticeable by beading as shown at c Fig. 111. By a further line of beading shown at f the flexible edge of the divinity circuit cover is defined.

The book 0 is pasted on to' the inner lining, and full end linings (Z, (Z are pasted on to the inner cover, and the first and last signatures of the book. These linings do not extend beyond the inner line of heading 7.

I claimas my invention:

The method of making flexible book covers which consists in preparing a flexible outer cover with rounded corners, covering one side of said outer cover completely with an adhesive, securing to said outer cover by means of said adhesive a lining of smaller dimensions and of stiffer material and with rounded corners in such a way that the edges of the outer cover and of the lining run parallel to each other, and then bending the protruding edge portions of the outer cover inward over the edge of the lining and securing the same to said lining by means of said adhesive, the edges of the stiffer inner lining acting as a guide, substantially as described.

in testimony whereof I have hereunto I signed my name in the presence of two subscribing witnesses.
